Week 9 - Attachment Feature Creation (Ribs & Screw Boss) - Challenge 1

AIM:

Create the rib for the Drill Handle considering the design rules and screws

TOOLING AXIS

To create the tooling axis we need study the class A surface and there is no gap between the surface. Create the point on the surface after create the tooling axis.

DRAFT ANALYSIS:

Draft analysis used to analysis the part for proper draft angle. It has 3 color scale green blue and red and maximum draft angle up to 3deg.Finally fix the compass on tooling axis on Class A surface.

In this draft angle we can absorb the some red color in class A after draft completion, that is occurred due to error Class A.

Class B surface

For making the B surface offset done from 2.5mm Class A.

After offset we can observed there is patches in Class B.

The Areas where the B-surface has issues are corrected by closing them using commands like join (which is helps to remove the surface), Multiple extract and trim.

Finally I made with edge fillet in trimmed area, and verified boundary.

Class C surface

In C class surface we have to create the edge surface of the door handle.

For this I use the sweep command for creating the surface and need to trim.

In class B I used sweep command and the extra surface on boundary.

Closed surface

Finally i done the closed surface command to conform all surfaces are closed.

Creation of Rib

Rib is used for additional support for the part. Create a plane on the surface and draw a sketch of the line on the surface. Further do extensions on that sketch perpendicular from a plane.

Creation of Screw boss

This is used for to assemble the molded part.

Draft analysis

Here i done the draft analysis is to conform the drafting we made 3deg. Because 3deg is maximum permissible for part.
